Well.... I bought it anyway... I didn't find something better until "AFTER" I ordered it....

But , it was special order.... No Return....

Anywho , Moving on.... Finding how to cut out the holes for the prop was a little difficult...

A flat pattern was close.... but , tilting the pattern on the angle that would be traced on the spinner

changed the way the prop hole looked....

I ended up making a spinner "Mock up"...

I covered my spinner with thin plastic....

and made a batch of paper mache paste... Flour , water , salt

Torn some strips of news paper.... and gave it a light coat....

After it dried , I coated the outside with Elmers Glue.... That helped "Stiffen" it up more...

From there , I traced my pattern after I put lines on the Mock up....

Now , I have a MUCH BETTER idea about the "cut outs"....

I modified my pattern , until I thought it was close enough to transfer the cut outs onto the spinner....

After , I still need to trim the Aluminum more for the Final fit....

Towards the end , I had enough clearance to mount the "Back Plate"....

But after final assy. I'll do a final trim Minimum 1/8" clearance...

Gotta Fly... Mike & "Jaz" in MN..Even though this "did" work for me.... If I ever do something like this again.... I Won't use paper Mach'e... It was a little too flimsyand it took days to dry.... Instead , I'd cover the spinner like I did... and use a thin coat of Fiberglass cloth and resin...This would hold the shape BETTER....

Sometimes you just have to take the leap and build your wings on the way down... Gotta Fly...
